Sulfur‐Boron Lewis Pair‐Catalyzed Hydrohalogenation of Alkynes via Formal Hydrogen Atom Transfer

Angewandte Chemie, EarlyView.
A sulfur‐boron Lewis pair enables the stereodivergent hydrohalogenation of alkynes with exclusive Markovnikov selectivity. Mechanistic studies support a proton transfer‐electron transfer (PT‐ET) sequence for vinyl radical formation rather than a concerted hydrogen atom transfer (HAT) pathway.

Dopant‐Tailored Matrices: A Crystal Engineering Strategy for Organic Room‐Temperature Phosphorescent Host–Guest Systems and Beyond

Angewandte Chemie, EarlyView.
Rather than selecting dopants to match a pre‐existing host matrix, the dopant‐tailored matrix strategy involves rational engineering of host matrices around a preselected class of dopants by targeting matrix packing motifs that promote synergistic host‐dopant interactions upon doping.

1,2‐Bis(boronate) Arenes by Borylation Directed Borylation

Angewandte Chemie, EarlyView.
Boron electrophiles derived from tetrabromo‐pyrazaboles and AlCl3 affect the regioselective vicinal double C–H borylation of a range of arenes and polycyclic aromatic hydrocarbons (PAHs). A subsequent pinacol installation step then affords the vicinal bis‐boronate ester‐substituted arene/PAH.

Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

Angewandte Chemie, EarlyView.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...
